随着西气东输工程的深入开展 ,如何保证天然气大口径流量计量的准确度越来越显得重要。这篇论文介绍了一座国外高压大容量流量仪表检定站 ,并从设计标准的分析着手探讨了这套装置的组成、流程、设备和仪表及计算机数据采集系统 ,希望能为国内天然气检定系统的开发研制提供参考。 With the deepening of the West-East gas pipeline project, it is more and more important to ensure the accuracy of large-bore natural gas flow measurement. This paper introduces a foreign high-pressure mass flow meter verification station, and from the design standards analysis set out to explore the device’s composition, processes, equipment and instrumentation and computer data acquisition system, hoping for the development of the domestic natural gas verification system Development for reference.
